GAS-METER FRAME.

SPECIFICATION forming part of Letters Patent No. 490,149, dated January17, 1893. Application tiled .Tune 15, 1892. Serial No. 436,819. (Nomodel.)

To all whom, it 'may connerie:

Be it known that I, HUGH LOGUE, a citizen of the United States, and aresident of Philadelphia, Pennsylvania, have invented certainImprovements in Meter-Frames,ot which the following is a speciiication.

The object of my invention is to make the diaphragm frame of gas metersof a single sheet of metal properly stamped up, thus avoiding the cornerjoints of the ordinary frame.

In the accompany-ing drawings:-Irigure l, is a perspective view of thetwo trames detached, between which is clamped the leather diaphragm;Fig. 2, illustrates the top frame prior to being bent up and flanged;Fig. 3 is a plan View of the top frame flanged; Fig. 4, is a plan Viewof the lower frame out prior to being flanged; Fig. 5, is a view of thelower frame flanged; and Fig. 6, is a sectional perspeetive view throughboth frames with the' leather between them.

The usual method of making the trames for meter diaphragme has been tomake each f rame of four stri ps of metal, soldered together at the endsso as to form a quadrangular trame, but these are not only costly tomanufacture owing to the time and care required in soldering the joints,but also on account of the difficulty of making a gas-proof jointbetween the frames and the leather, as the overlapping cornersnecessitate careful filling and packing in order to prevent leakage, butby stamping the frames out of a single sheet of metal, the overlappingjoints are dispensed with, and when the leather is once clamped downupon the frame, it will be perfectly even and gas-proof avoiding thenecessity of packing.

The underframe A has adeep outside ilange af, and a shallow insidellange b. This inner llange is turned outward and lapped over the outerface of the frame A so as to present a smooth edge for the leather. Theoutside flange is of a sufficient height to lap over the -frame B andthe leather so as to hold the trame I3 firmly upon the leather making agas-proof joint. The frame B is also provided with an internal ilange CZwhich is turned over upon theoutside ot' the frame B presenting a smoothedge for the leather, the same as the flange b of the frame A.

The plates cut from the interior of a flat diaphragm meter arepreferably cut and the frames used as shields for the leather, as

shown in Figs. 3 and 5, thus all the metal is utilized in themanufacture.

The shields are cut and the edges folded over as shown in the ligures,the shields being placed on both sides of the leather and securedthereto in any suitable manner, as shown in Fig. 6.

I claim as my inventionzm l. The combination in a meter diaphragm, ofthe quadrangular open frame A made from a single sheet of metal, havingan external clamping tiange, and an internal flange, a quadrangularframe B also made from a single piece of metal, and having an internalflange, with leather or equivalent material mounted between the twoframes, the clamping ange of the frame A being turned down over theframe B, substantially as described.

2. The combination in a meter diaphragm, of the quadrangular internallyflanged frames A and B each made from a single sheet "t metal, one framehaving an external clamping flange adapted to pass over the other, twosets of triangular ilanged shields made from the metal out from theframes A and B, with leather clamped between the two sets ofquadrangular shields, the internal flanges of the frames A and B, andthe ilanges of the triangular shields being bent outward so as to formsmooth edges for the leather, thus preventing the cutting of the saidleather, substantiallv as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing Witnesses.

HUGH LOGUE.
